I think they had a slow day in the engineering staff meeting! "O. K. people, let's make something really ridiculous that adds cost to our cars. Any ideas?"
Seriously though, I can see it helping in Saudi Arabia or Arizona to control vapor lock, but I can't see it as a performance enhancement. If cool fuel was beneficial we would have refrigerated fuel tanks.... (light bulb above my head)...anybody know the phone number for MB Engineering??
